Logic

The Christian worldview is not a mere assumption. It is the worldview that makes knowledge possible (Proverbs 1:7; Colossians 2:3). It alone provides the justification for those things we need for reasoning—such as laws of logic and uniformity.

The common accusation that the presuppositionalist uses circular reasoning is actually true. In fact, everyone uses some degree of circular reasoning when defending his ultimate standard (though not everyone realizes this fact).
